The NACHI thrust ball bearing model 51102 is a high-precision unidirectional axial bearing designed to handle medium to heavy axial loads. It features a 15-millimeter inner diameter, 28-millimeter outer diameter, and a total thickness of 9 millimeters. The bearing includes two hardened steel washers and a set of steel balls with surface hardness between 60 and 64 HRC. The rings are made from SUJ2 chrome alloy steel with high compressive strength. Dimensional accuracy meets ISO 3245 standards with a P6 tolerance class. The optimized raceway geometry ensures uniform load distribution and minimizes frictional heat during high-speed operation.
The manufacturing process of the NACHI 51102 thrust ball bearing involves controlled heat treatment and precision grinding to achieve micron-level tolerances. It operates reliably within a temperature range of minus 20 to plus 120 degrees Celsius. Lubrication is typically provided by lithium-based NLGI-2 grease or ISO VG 46 industrial oil. The permissible rotation speed is up to 5000 rpm with grease and 7000 rpm with oil. This model is widely used in pumps, gearboxes, vertical motors, and precision industrial equipment.
